You're absolutely right. As a matter of fact, some people seek out the testing. We've heard that some of the dealers are actually sending people in to have the drugs checked, because they don't want to be giving fentanyl to their cocaine users. Anyway....
I don't think it's an issue around perpetuating use. We did a pilot study at InSite, the supervised injection service site in Vancouver. Some people didn't test. People go to InSite because they don't want to die from their drug addiction. It's an opportunity for us to intervene, to treat them with respect, to give them the chance to get off that cycle they're in. We don't see it as a way of perpetuating the use or encouraging people to use. What we find is that every day they stay alive, it's an opportunity to get off that cycle.
The naloxone keeps people alive. What we're finding is that people will check their drugs, and because you have to use a bit of your drug, if it's hard to come by and you're in that situation, you might not want to do that. We're finding that people will do it after they've overdosed to see if that was the cause of it.
It's a challenge still, because with the tests that are available for drug checking, we don't know the parameters. They're not designed for drugs. They're designed for urine testing. We don't have good drug checking capabilities yet, but we're working on it.
